Queue segfaults when iterating a copy

[robincafolla]

PHP version: PHP 7.2.16-1+ubuntu16.04.1+deb.sury.org+1

Iterating directly on a copied queue seg faults:

use Ds\Queue;

$queue = new Queue();
$queue->push(1, 2, 3);

foreach ($queue->copy() as $value) {
  // Segfaults
}

The work around is to store the copy in a new variable:

use Ds\Queue;

$queue = new Queue();
$queue->push(1, 2, 3);
$copy = $queue->copy();

foreach ($copy as $value) {
  // No Segfaults
}

• PHP error: Process finished with exit code 135 (interrupted by signal 7: SIGEMT).
• dmesg on off chance it helps: [ 6054.379466] traps: php7.2[11022] trap stack segment ip:7f96bd8f584c sp:7fff08522930 error:0 in ds.so[7f96bd8e2000+2f000]
